Brand reputation / product line loyalty
Many reviewers say they already use other Round Lab Dokdo products (toner, cleanser) or the Birch Juice cream and bought this cream to complete the routine or because they trust the brand overall.
Repurchase / holy grail status
A large number of reviews explicitly mention this being their 2nd, 3rd, 4th, or 5th repurchase, indicating strong repeat-buy behavior driving sales.
Suitability for sensitive/dry skin reputation
Consumers with eczema, sensitive, or very dry skin sought this out specifically because of its reputation for being gentle, unscented, and moisturizing without irritation.
Seasonal need (winter dryness)
Many buyers purchased it specifically to combat winter dryness, citing it as their go-to cold-weather moisturizer.
Gifting
Several reviewers bought it as a gift for mothers, sisters, husbands, or friends with sensitive or dry skin, suggesting gifting is a secondary purchase driver.
